Abstract

Systems and methods are provided for substantially reducing undesired cumulative effects by preferentially heating the active particles. By preferentially heating the active particles, the active particles are “cleaned” of substances that may reduce or negate particle activity. In addition, preferential heating may reduce active particle adsorption of binder.

Claims

exact text as granted — not AI-modified
1. An adsorption article, comprising:
 first and second substrates produced from fibers obtained by extruding a mixture comprising active particles having a removable protective layer, the first and second substrates comprising the active particles of the mixture; 
 an activated carbon layer between the first and second substrates, the activated carbon layer comprising activated carbon particles; and wherein, 
 the activated carbon particles and the active particles are adapted to be preferentially heated compared to at least the first substrate and second substrate in a process for producing the adsorption article, the preferential heating resulting in a higher percentage of active particle activity. 
 
     
     
       2. The adsorption article defined in  claim 1 , wherein the first and second substrates are fixed together with a binder. 
     
     
       3. The adsorption article defined in  claim 2 , wherein the binder fixes the activated carbon particles to the first, second, or both substrates. 
     
     
       4. The adsorption article defined in  claim 1 , wherein the activated carbon particles are synthetically derived activated carbon particles. 
     
     
       5. The adsorption article defined in  claim 1 , wherein the activated carbon particles have a mean diameter ranging between 1-500 μm. 
     
     
       6. The adsorption article defined in  claim 1 , wherein the activated carbon particles have a mean diameter ranging between 250-500 μm. 
     
     
       7. The adsorption article defined in  claim 1 , wherein the activated carbon particles have a mean diameter ranging between 180-250 μm. 
     
     
       8. The adsorption article defined in  claim 1 , wherein the activated carbon particles have a mean diameter ranging between 90-125 μm. 
     
     
       9. The adsorption article defined in  claim 1 , wherein the activated carbon particles have a mean diameter ranging between 1-80 μm. 
     
     
       10. The adsorption article defined in  claim 1 , wherein the activated carbon particles comprise a mixture in which approximately 50% of the particles have a mean diameter ranging between 180-250 μm and the other approximate 50% of the particles have a mean diameter ranging between 90-125 μm. 
     
     
       11. The adsorptive article defined in  claim 1 , wherein the active particles comprise activated carbon. 
     
     
       12. The adsorptive article defined in  claim 1 , wherein the activated carbon particles occupy a predetermined loading range between 16-132 g/m 2 . 
     
     
       13. The adsorptive article defined in  claim 1 , wherein the activated carbon particles occupy a predetermined loading range between 38-76 g/m 2 . 
     
     
       14. The adsorptive article defined in  claim 1 , wherein the activated carbon particles occupy a predetermined loading range between 55-65 g/m 2 . 
     
     
       15. An adsorption article, comprising:
